PENN PLAX DELUXE BUBBLE DISK
The Penn Plax Deluxe Bubble Disk creates the aeration and surface agitation needed for a healthy pond or aquarium.
Great to use in aquarium decorations to create a “volcano” of bubbles. Breaking bubbles at the surface temporarily clears accumulated organic “slime”, allowing oxygen into the water and carbon dioxide out. Round design provides an interesting effect.
For use in freshwater or marine aquariums and ponds. Uses standard airline tubing.
